A research team headed by Dr. Scott Bultman (University of North Carolina) has identified an essential role for the mammalian SWI/SNF chromatin remodeling complex in red blood cell formation. The authors generated a partial loss-of-function mutations in the ATPase domain of the SWI/SNF catalytic subunit, Brg1, effectively uncoupling its ATPase and chromatin remodeling activities.
Brg1-mutant mice die at mid-gestation due to defective erythropoiesis. Commenting on the relevance to human disease, the authors pointed out that "although much is known about the biochemistry of SWI/SNF chromatin-remodeling complexes, not as much is known about their role in development and physiology.
This Brg1 mutation is significant because it reveals a role for these complexes in beta-globin regulation and erythropoiesis and may provide insight into common ailments such as beta thalassemia and anemia."

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
